Some modifications are imposed on genetic algorithm to improve its capability and efficiency while being hybridized with Simplex method. Benchmark test examples of structural optimization with a large number of variables and constraints are chosen to show the robustness of the algorithm.hybrid algorithm, optimization, genetic algorithms, Nelder Mead simplex, trusses2946http://ijoce.iust.ac.ir/browse.php?a_code=A-10-1-3&slc_lang=en&sid=1HosseinRahami18003194753284600801800319475328460080NoAliKaveh18003194753284600811800319475328460081Yes
